Nkhani yabwino kwa okonda chokoleti-asayansi mwina adapeza njira yopangira maswiti kukhala athanzi.
Kumwa chokoleti chakuda pang'onopang'ono kwatamandidwa chifukwa cha antioxidant katundu wake, koma si aliyense amene angayambe ndi kuwawa kwake kolemera.
Gulu lofufuza kuchokera ku American Chemical Society (ACS) lidapeza kuti kuwonjezera pakhungu la ufa wa chiponde ku chokoleti yamkaka kumapangitsa kuti ma antioxidants azikhala ochulukirapo kuposa mitundu yakuda popanda kusokoneza mawonekedwe ake okoma kapena opepuka.
Akaperekedwa kwa gulu la oyesa kukoma, oposa theka amakonda chokoleti cha mkaka wa mtedza kuposa omwe amagulidwa m'masitolo lerolino.
Wolemba woyamba Dr. Lisa Dean anati: "Lingaliro la polojekitiyi lidayamba ndi kuyesa zochitika zamoyo zamitundu yosiyanasiyana yazaulimi, makamaka zikopa za mtedza."
"Cholinga chathu choyamba chinali kuchotsa phenols (gulu la mankhwala okhala ndi antioxidant katundu) pakhungu ndikupeza njira yosakaniza ndi chakudya."
Mtedza ukawotchedwa mu batala wa nati kapena mu confectionery, mapepala ake ofiira amatayidwa, zomwe zimawononga matani masauzande ambiri chaka chilichonse.
Izi zimasiya lignin ndi cellulose (ziwiri zomwe zili m'makoma a cellulose), zomwe zimawonjezera kuchuluka kwa chakudya cha ziweto.
Ufa wotsatira umasakanizidwa ndi maltodextrin (chakudya chodziwika bwino) kuti zikhale zosavuta kuziyika mu chokoleti cha mkaka.
Dr. Dean anati: “Phenolic resin ndi owawa kwambiri, choncho tiyenera kupeza njira yochepetsera maganizo amenewa.”
Akagwiritsidwa ntchito ndi oyesa kukoma, gululo lidapeza kuti limatha kuzindikira zochulukirapo kuposa 0.9%, zomwe zidakhudza kukoma kapena kapangidwe kake.
Zotsatira zomwe zidaperekedwa pamsonkhano wapagulu wa ACS 2020 zikuwonetsa kuti opitilira theka la oyesa kukoma amakonda ngakhale chokoleti yamkaka ya phenol 0,8% kuposa mitundu wamba, ndipo zochita za antioxidant zachitsanzozi ndizokwera kuposa za chokoleti chakuda.
Anthu omwe amasankha chokoleti chakuda kuti apindule ndi thanzi angazindikirenso kuti chokoleti chakuda ndi chokwera mtengo kuposa mitundu ya mkaka chifukwa cha kuchuluka kwa koko.
Asayansi amakhulupirira kuti kuwonjezera khungu la chiponde ku chokoleti cha mkaka kungapangitse thanzi pamtengo womwewo.
Amavomereza kuopsa kwa ziwengo, koma chokoleti chilichonse chokhala ndi mtedza chiyenera kulembedwa kuti chili ndi zowawa wamba.
Pofuna kuthetsa vutoli, asayansi akukonzekera kuyesa malo a khofi ndi zinyalala zina mofananamo.
Akuyembekeza kuti apezanso ngati ma antioxidants omwe ali m'zikopa za mtedza amatha kuwonjezera moyo wa alumali wamafuta a mtedza, omwe amawola mwachangu chifukwa chokhala ndi mafuta ambiri.
